Thanks for your insights about glass slumping. I might say these pieces were made that way, except that they are so thin and delicate. The pictures don't really show that they are very fragile and one person even suggested they could be salts. But that wouldn't be possible because they are far too thin for any use except as art glass.

The age of these items would prevent me from saying they were from Israel originally. I know my mother aquired these pieces in the 60's in the states.
